Size doesn't matter, because you're only getting as much air as you're smallest open will allow

2.5" doesn't matter really unless you plan on getting a lot more work done. However, everyone seems to want 3" intakes, so I decided to change to 3" ones. It is too much coordination to stock 2.5", 3", black, blue, red, yellow couplers, 4 different filters, etc.

By changing to 3" CAI, the price will be a bit higher, but it will allow me to directly compete with other manufacturers at a cheaper price and not get too complicated.

awww I thought you were done making them? whats the new price for them?

I have decided to start again, but I'm moving a bit upscale. The new ones will be 3", and the details are in the "general" performance section stickied.
